So far, distinct fossils from the Cambrian explosion with o

outlines of soft tissue have been found at the Burgess Shale in Canada, as well as some by the Chengjiang River in Yunnan province. The

newly discovered fossils provide a completely different ecosystem of organisms that lived around the same time, the study said.

Unlike other Cambrian fossil troves, the Qingjiang biota appears to conta

in a high proportion of jellyfish and comb jellies, which are extremely rare at other sites.

Zhang Xingliang, a professor at Northwest University and co-author of the p

aper, said that compared with the Chengjiang biota in the shallow water along the coast, Qi

ngjiang biota lived in deep ocean, making the two biota complementary in their scientific significance.

“The treasure trove of the Qingjiang biota provides an exciting opportunity to explore how paleoenvironmental conditi

ons influenced ecological structuring and evolutionary drivers during the Cambrian explosion,” said Allis

on Daley, a paleontologist at the University of Lausanne in Switzerland, who was not involved in the study.
